Fury: "Fury operatives use implants to fuel biotics and their incredible
movement speed. These operatives wind an unpredictable path on the
battlefield, moving in and out of combat before returning to unleash a
sweeping biotic attack on their unsuspecting targets."

Demolisher: "The Demolisher uses grenades to attack at range and to
terrorize the battlefield. Demolishers can also create a supply pylon
that stocks allies with an unending reserve of grenades and thermal
reloads."

Paladin: "The Paladin carries a powerful omni-shield onto the
battlefield to block enemy fire. The Paladin also uses the shield as a
heavy-melee weapon that, when modified with incindiery or cryo upgrades,
creates a devastating combination attack."

Shadow: "Shadow infiltrators use implants to dramatically improve
agility, making them slippery combatants on the battlefield. Their
monomolecular blades are a menace from cover and close range."

Slayer: "Slayers use implants to dramatically improve mobility. Their
dizzying sword attacks can hit multiple opponents, and the Slayer's
ability to slip fire makes them hard to pin down on the battielfield."
